How Challenging is Your Environment?


Hazardous Environments

The TopWorx GO Switch is designed to function where high temperature, pressure, radioactivity and potential for combustion are constant challenges. In addition to high temperature +204 °C (+400 °F), cold temperature -50 °C (-58 °F), and sub-sea 7,010 m (23,000 ft) applications, these products are suitable for use in Flameproof/Explosion Proof, Non-Incendive, Intrinsically Safe hazardous areas with both global and regional certifications available.

A Versatile Combination of Proximity Switch and Limit Switch

The TopWorx GO Switch uses magnets to detect a ferrous metal or magnetic target, and like other proximity switches has no exposed, moving parts. Like a limit switch, it provides highly precise readings and is suitable for a wide variety of industrial applications. By combining these features, the GO Switch requires far less maintenance than traditional limit switches and performs within ruggedized and harsh environments that often prohibit the use of other technologies such as inductive or capacitive sensors.

TopWorx GO スイッチのスクエアモデルは、従来の機械式リミットスイッチの理想的な代替品です。 この製品は通常、精度要求が低く、サイドセンシングとエンドセンシングの変動が少ない拡張センシング用途に使用されます。 2 つの内部磁石のうち、優勢な磁石が封入接点を支持する電機子の位置に影響を与えます。 鉄や磁性体のターゲットが検出エリアに入ると、磁束が変化して一方の磁石がより優勢となり、その結果、アーマチュアが接点を閉じて信号が出力されます。
